Name(s): Creator (cre): Hoffman, Jordan Michael, Thesis advisor (ths): White, Bradley N, Degree committee member (dgc): Nocera, Joe, Degree committee member (dgc): Schaefer, James, Degree granting institution (dgg): Trent University
Abstract: <p>Most delphinids produce narrowband frequency-modulated whistles with a high level of plasticity to communicate with conspecifics. It is important to understand geographic variation in whistles as signal variation in other taxa has provided insight into the dispersal capabilities, genetic divergence and isolation among groups, and adaptation to ecological conditions. I investigated… more

Name(s): Creator (cre): Nixon, Katrina Leigh, Thesis advisor (ths): Pond, Bruce A, Thesis advisor (ths): Patterson, Brent R, Degree committee member (dgc): Schaefer, James, Degree granting institution (dgg): Trent University
Abstract: <p>Livestock predation by wild predators is a frequent and complicated issue, often cited as a significant factor in the decline of livestock production and justification for killing predators. Coyotes (Canis latrans) are the primary predators of sheep in Ontario. Some farms appear to be more susceptible to predation than others, despite the use of mitigation techniques. I explored land… more

Conservation Genetics of Woodland Caribou in the Central Boreal Forest of Canada

Name(s): Creator (cre): Thompson, Laura Marie, Thesis advisor (ths): Wilson, Paul J., Degree committee member (dgc): Pond, Bruce, Degree committee member (dgc): Schaefer, James, Degree granting institution (dgg): Trent University
Abstract: <p>Maintaining functional connectivity among wildlife populations is important to ensure genetic diversity and evolutionary potential of declining populations, particularly when managing species at risk. The Boreal Designatable Unit (DU) of woodland caribou (Rangifer tarandus caribou) in Ontario, Manitoba, and Saskatchewan has declined in southern portions of the range because of increased… more
